Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I received the following from Thawte, who is currently sponsoring a few forums, and thought the security minded folks at LQ might be interested.
Thawte technologies inc., the second largest digital trust service company worldwide, has announced the launch of their fourth Crypto Challenge competition and Lunch Hour Challenge campaign. Together these campaigns are aimed at Cryptography hobbyists of all levels: from beginners wanting to learn, to experts looking for a challenge.
The Crypto Challenge is a fun, on-going competition aimed at Cipher hobbyists able to crack level 3-4 of Simon Singh's Cipher Challenge . The mysterious cipher genius Mr X develops the Crypto Challenges to be cracked. The first person to crack the code, wins the main prize: a Nikon Cool Pix SQ digital camera, there are runner's up prizes too.
The Lunch Hour Challenge is a recent addition to the Crypto Challenge, developed for people interested in Cryptography but still learning, and experts that enjoy the hobby but do not have the time to decrypt a difficult cipher. This challenge is purely for the fun of it - there are no prizes and no rules.
